ABSTRACT: Sweet cassava breeding programs are focused on the development of bio fortified cultivars that combine significant amounts of carotenoids in their reserve roots with desirable agronomic. The objective of this research was to evaluate agronomic and biochemical traits in sweet cassava clones with roots that have pink pulp. The nine genotypes were evaluated in two seasons in a randomized block design with three replications. Among the evaluated clones, the following stood out: i) for the height of the first branch (390/08, 345/08 and the control IAC 576-70); ii) for plant height (390/08, 345/08 e 378/08); iii) for shoot weight without original steam cutting (390/08, 406/08, 378/08 e 341/08); iv) for the percentage of starch in roots (378/08,...

Abstract: The objective of this work was to estimate the genetic, phenotypic, and environmental parameters of 113 barley accessions (Hordeum vulgare), previously selected based on high yield, in an irrigated production system in the Cerrado (Brazilian savanna), for use in breeding programs in Brazil. The experiment was conducted in 2013 at two sites in the Federal District, using a randomized complete block design with three replicates. The evaluated traits were: grain yield, kernel plumpness, thousand grain weight, plant height, lodging, and days to heading. Significant differences were observed between environment and accessions for all studied traits, as well as genotype x environment interaction.

The objective of this work was to adapt the application of electrolytic conductivity and potassium leaching tests to assess the viability of cryopreserved embryos of 'Anão Verde do Brasil de Jiqui' (AVeJBr) coconut. The zygotic embryos were excised, sterilized and subjected to four cryoprotectant treatments combined with three incubation times (12, 16 and 20 hours), totaling 12 treatments. The pre-treatment of mature zygotic embryos of AVeJBr coconut using a cryoprotectant with 1.75 mol L-1 of sucrose + 15% glycerol for 12 and 16 hours promoted lower embryo humidity and increased viability in electrolytic conductivity and potassium leaching tests. Samples with ten embryos are sufficient for electrolytic conductivity analysis in cryopreserved or...

A macaúba (Acrocomia aculeata) é uma palmeira oleaginosa e o extrativismo de seus frutos é de grande importância socioeconômica para os pequenos produtores rurais. O objetivo deste trabalho foi avaliar a variabilidade genética e obter informações sobre o controle genético de características morfológicas relacionadas ao crescimento e vigor da macaúba. Foram coletadas 51 progênies em Minas Gerais e São Paulo, as quais são integrantes do banco ativo de germoplasma da Universidade Federal de Viçosa. Doze meses após o plantio, essas progênies foram avaliadas quanto ao crescimento da planta (cm) e número de folhas emitidas. Estas características apresentaram grande variabilidade entre as progênies. As estimativas dos coeficientes de herdabilidade foram de 87% e...

BIODISCOVERY AND INTELLECTUAL PROPERTY RIGHTS: A DYNAMIC APPROACH TO ECONOMIC EFFICIENCY

Dedeurwaerdere, Tom; Krishna, Vijesh V.; Pascual, Unai.

This paper examines the use the use of economic incentives for knowledge generation through biodiscovery, in the particular case of the use of a highly valuable biogenetic resource stock from the South for industrial/research input. The focus is on a dynamic approach to contracting and property rights building upon insights from institutional and ecological economics. Two important conclusions come out of this analysis. First, it highlights the necessity to go beyond standard market approaches to economic valuation in order to address the issues of future possibilities of use and innovation and the integration of the different stages in the process of value creation. Second, it shows the necessity of developing alternatives to the current intellectual...

Biometric variability of goat populations revealed by means of principal component analysis

Genet. Mol. Biol.

Pires,Luanna Chácara; Machado,Théa M. Medeiros; Araújo,Adriana Mello; Olson,Timothy A.; Silva,João Batista Lopes da; Torres,Robledo Almeida; Costa,Márcio da Silva.

The aim was to analyze variation in 12 Brazilian and Moroccan goat populations, and, through principal component analysis (PCA), check the importance of body measures and their indices as a means of distinguishing among individuals and populations. The biometric measurements were wither height (WH), brisket height (BH) and ear length (EL). Thorax depth (WH-BH) and the three indices, TD/WH, EL/TD and EL/WH, were also calculated. Of the seven components extracted, the first three principal components were sufficient to explain 99.5% of the total variance of the data. Graphical dispersion by genetic groups revealed that European dairy breeds clustered together. The Moroccan breeds were separated into two groups, one comprising the Drâa and the other the...

This paper addresses the value of bioprospection for genetic resources (GR) and traditional knowledge (TK) from the South for industrial/research input. The focus is on a dynamic approach to contracting and property rights building upon insights from evolutionary institutional economics. Drawing on a unique 'access and benefit sharing' (ABS) bioprospecting contract from the Western Ghats, India, we show how the monetary value of plant genetic information from the traditional knowledge holders' perspective can be assessed using a contingent valuation modelling approach. While the study allows the identification of such values from one of the main stakeholder's (i.e, the Kani community) perspective, it also allows to point out some of the key gaps in the...

Brazilian Germplasm Bank: conservation of genetic resources of sheep and goats.

FONSECA, J. F. da; SILVA, K. de M..

Brazil is known for its enormous natural animal resources, typically associated with a large diversion of biomes. Although they do not originate in the country, the sheep and goats that were incorporated by settlers after the discovery became the so-called locally adapted animals. This adaptation obeyed the environmental challenges imposed, being more severe in the semi-arid zone - Caatinga biome. Similar to the African savannah, important and unique genotypes of small ruminants live in the Caatinga. Most of them are under some degree of extinction risk mainly because there is no economic interest and/or indiscriminate reproduction with commercially exploited sheep and goats around the world, such as Dorper and Boer, respectively. These specimens were...

Na última década, a diversificação de cultivares e o aumento da oferta de uvas sem sementes no mercado interno são apresentadas como mudanças na cadeia produtiva da uva de mesa no Brasil. Essas mudanças acompanha-ram as tendências de crescimento dos programas públicos e privados de mehoramento genético de uvas de mesa no mundo, onde dezenas de cultivares são lançadas a cada ano no mercado global. No Submédio do Vale do Submédio do Vale do São Francisco são cultivadas mais de 20 cultivares de uvas de mesa desenvolvidas pela Embrapa e por empresas privadas internacionais de melhoramento genético. A nova cultivar BRS Tainá apresenta características desejáveis em uvas para o consumo in natura como bagas firmes, com boa aderência ao pedicelo e traços minúsculos...

VIEIRA, E. A.; FIALHO, J. de F.; SILVA, M. S..

O objetivo do trabalho foi caracterizar acessos de mandioca com coloração da polpa da raiz branca, creme, amarela e rosada, por meio de descritores morfológicos. O experimento foi conduzido entre 2006 e 2007, em área experimental da Embrapa Cerrados. Foram avaliados,por meio de 33 descritores morfológicos, 16 acessos de mandioca mantidos no Banco Regional de Germoplasma de Mandioca do Cerrado (BGMC), sendo 1 acesso com coloração da polpa da raiz branca, 2 com coloração da polpa da raiz creme, 4 com coloração da polpa da raiz rosada e 9 com coloração da polpa da raiz amarela. Entre os 33 caracteres qualitativos avaliados, 27 (82 %) apresentaram variabilidade, o que revela a existência de ampla divergência morfológica e a eficiência desses marcadores na...

Las secuencias de ADNr han sido útiles para clasificar a muchos basidiomicetos, debido a que se pueden caracterizar en muchos niveles taxonómicos en base a sus regiones conservadas y variables. Tal es el caso de los Ustilaginales, los cuales tienen importancia por sus implicaciones económicas adversas, por lo que han sido estudiados mediante algunas de estas técnicas, especialmente con la región ITS del ADNr, ya que muestran diferencias a nivel de nucleótidos, permitiendo establecer la diversidad genética de hongos a nivel inter e intra-específico. En este contexto se tiene a Ustilago maydis, el cual es un hongo que infecta al maíz produciendo el “huitlacoche” o “carbón del maíz” del cual existen estudios limitados sobre su características morfológicas y...
